Abstract

560,434. Converting. HEAYBERD, F. C., KRIMHOLTZ, J., and HEAYBERD & CO., Ltd., F. C. Dec. 31, 1942, No. 18588. [Class 38 (ii)] [Also in Group XXXVII] A bimetal dished annulus 1 is held to a base 2 by a rigid bracket 3 attached to one side of the ring; A contact 6 is borne on the opposite side which snaps into and out -of contact with an adjustable fixed contact 7. In an example, Fig. 5 (not shown), the bracket is in heat conducting relation; through a mica strip, with a cooling fin on a dry contact rectifier, the switch being arranged to open the main, transformer, or rectified current circuit, on overloading.
